On the edge of Tabwell lies a forest where the dark secrets of the past wait to be uncovered. It all began when Jenny Adams first dreamed of a young girl imprisoned in a dark attic. Now, over six years later, she's back where the nightmares started. Mosswood has been transformed into a successful adventure park, and it is there Jenny meets troubled, flame-haired teen Bailey Rosales, and Cody Nelson, a seven-year-old who has some very special friends. Dead friends. Why is Dennis Blakely, the park manager, tormented by visions of his own horrific demise, and why is an ex-councillor warning them to stay out of the forest at all costs? Once again, Jenny finds herself calling on the spirit of Amelia Root in the search for answers, but it is a search that leads the whole family into a terrifying confrontation with Tabwell's past and the secrets that lurk beyond the dark waters of Mosswood's lake.
